DETACHABLE SPICE CRUSHER UNIT Russian patent published in 2013 - IPC A47J42/38 

FIELD: personal use articles.

SUBSTANCE: invention relates to appliances for crushing solid food products, in particular - for manually-driven ones intended for crushing spices. The first component has a coaxial bushing with an axial inner hole the surface whereof is covered with dents. The second component has a coaxial hollow conic element with spikes, perpendicular to the element axis and diverging from the element walls into its base; between the spikes there are holes. The outer surface of the hollow conic element of the second component has dents. The hollow conic element of the second component is placed inside the axial hoe of the first component bushing. Between the dents of the first and the second components a space is formed wherein spice grains grinding occurs during the second component rotation relative to the first one. Specificity of the utility model consists in the fact that the first component has a coaxial support ring connected to the bottom butt-end of the bushing with connective strips, positioned radially and perpendicular to the component axis; the hollow conic element of the second component has a coaxial bottom support pin inserted into the inner hole of the first element support ring. The inner surface of the hole in the coaxial bushing of the first component has two groups of straight dents, each group positioned on one of the two adjacent conic sections of the inner hole with varied conicity. The outer surface of the hollow conic element of the second component has two group of screw-shaped dents; the group of higher dents encloses two adjacent conic sections of the outer surface with varied conicity, while the lower group of dents is positioned on the top section with greater conicity.

EFFECT: reliability enhancement; service life extension, increase of uniformity and reduction of size of the resultant grind particles, reduction of the quantity of unground coarse grains in the residue, improvement of efficiency of the crusher operation are ensured by the fact that the detachable spice crusher unit contains two coaxial components inclusive of the first component having means for attachment to the necks of the container with spices and the second component rotated relative to the first one and placed thereon.
